The contrast between gear drive and pulley drive
The disadvantages of belt drive are: the belt wheel drive is flexible and smooth, the transmission is less efficient and cannot maintain accurate transmission ratio. When the belt wheel drives the same large circle force, the size of the outline and the pressure on the shaft are greater than the meshing drive. The belt has a shorter life span. The diameter of the pulley of all kinds of mechanical equipment is its own pulley According to the deceleration, the speed of the machine is designed according to the speed of the machine.
The characteristics of pulley drive are: the belt wheel drive can mitigate the load impact. The belt wheel drive is smooth, low noise and low vibration. The structure of the pulley drive is simple and easy to adjust. The belt wheel's manufacturing and installation accuracy is not as strict as meshing drive; The belt wheel drive has the function of overload protection; The two shafts of the pulley drive are larger in range.
The gear transmission is characterized by the steady transmission of the gears, the accuracy of transmission, the reliability of the work, the high efficiency, the long life, the power, the speed and the size of the gear. Transmission power, for example, can range from small to hundreds of thousands of kilowatts; The speed is up to 300m/s; The gear diameter can range from a few millimeters to more than 20 meters. But the manufacturing gear requires specialized equipment, and the meshing drive produces noise.
